Worker. Head capsule and pilosity yellow. Postclypeus moderately inflated, Pcl/W, 0-28. 

 Apical teeth of mandibles very long, La/Li, 1-07, R A /Ri, 129; subsidiary marginal tooth of left 

 mandible just clear of molar prominence in surface view, La/Li .L m , 22-55; anterior edge of first 

 marginal tooth of right mandible shorter than that of second, RA/Ri-Rm. 3°i5- Fore tibia 

 moderately swollen, Ti/T w , 3-92, third apical spur about two-thirds length of other two. 

 Mesenteric junction with proctodeum transverse, to right of malpighian knot; enteric valve- 

 seating lateral or slightly dorsolateral in unopened abdomen; internal cushions of enteric 

 valve moderately developed, with scaly surface, posterior margin of each scale fringed with 

 several small spines. Membranous wall of valve beyond cushions with very numerous fine but 

 distinct spicules arranged in 15-20 rows, only slightly broken into fringed lobes between posterior 

 ends of cushions. Other characters in generic diagnosis.
